So glad you posted this Josh. I struggle with similar questions. I find it is pretty easy to talk your way into (and out of) what fits this criteria when you are working on an investment opp. The criteria for “NEED to exist” could be dynamic based on the world around us too.
For me, when a company has the potential to change/shape the industry they are in…it starts to fulfill that desire to work on impactful things. When the “after” for the category will look different if the company gets to scale, I know its worth spending time on.
